Conservatory Cleaningacross Cheshire & the North WestLight back in the room you stopped using.
Roof panels, frames, finials, box gutters and glass cleaned properly: the green film and leaf debris removed from the surfaces you can see through, restoring the daylight the room was built for without stressing a single seal.
Fully insured, DBS checked, and every job photographed before and after.
What conservatory cleaning actually involves
Conservatory cleaning covers far more than the glass. The roof panels, ridge, glazing bars, box and valley gutters, finials, frames, cills and internal glass all contribute to whether the room feels bright and usable or dim and neglected. Most conservatories that owners describe as gloomy simply have several seasons of algae and leaf silt on the roof.
We clean using purified water fed through reach poles, gentle detergents where required, and hand detailing on glazing bars, seals and finials. Roof panels: glass or polycarbonate: are cleaned at low pressure, and box gutters and valleys are cleared of the leaf litter that causes leaks at the abutment with the house.
Because the difference is measured in light rather than in appearance alone, this is one of the few exterior jobs whose result you feel from inside as much as you see from outside.
Why professional work matters here
Conservatory roofs are fragile and non-load-bearing, and polycarbonate scratches almost as easily as it clouds. Pressure jetting past seals is a genuine cause of leaks, and standing or leaning on a roof panel is a genuine cause of falls. Reach-pole cleaning with purified water avoids all three: no contact load on the panels, no water forced past seals, and no smearing or spotting because the water dries residue-free.
Who this is for
-
Conservatories that have gone dim
Rooms across Cheshire that stopped being used because the roof no longer lets enough light through.
-
Orangeries and glazed extensions
Larger glazed structures with lantern roofs, flat roof glazing and substantial frame areas.
-
Properties with box gutter leaks
Where debris in the valley or abutment gutter is causing water to back up into the structure.
-
Homes going to market
A clean, bright conservatory photographs as extra living space; a green one photographs as a liability.
When it is needed
- Green film across the roof panels, especially on the shaded side
- The room feeling noticeably darker than it used to
- Leaf litter and moss visible in the box gutter or valley
- Black streaking down the frames and glazing bars
- Water ingress at the abutment where the conservatory meets the house
- Spring, before the room comes back into regular use
The cost of leaving it another season.
A conservatory that stops being cleaned tends to stop being used, and then the maintenance issues develop unnoticed.
The room becomes unusable
Light transmission through a green polycarbonate roof drops dramatically. Owners stop using the space and the maintenance stops with it.
Blocked box gutters leak into the house
The valley where the conservatory meets the wall is the single most common leak point, and it is almost always debris that causes it.
Seals and gaskets degrade
Constant damp, growth and trapped debris around gaskets shorten their life, and failed seals mean condensation and leaks.
Permanent staining on panels
Algae left in place on polycarbonate stains the surface and gets into the flutes, where it becomes very difficult to remove.
Frame discolouration
UPVC frames grey and oxidise on the same timeline as the roofline, and past a point cannot be fully restored.
Common mistakes we're called in to fix
- Pressure washing the roof, which forces water past seals and marks polycarbonate
- Climbing or leaning on a conservatory roof to reach the middle panels
- Cleaning the glass but never clearing the box gutter or valley
- Using abrasive cleaners on frames and glazing bars
- Assuming a leak means the structure has failed when the cause is usually a blocked gutter
Cleaning restores a room you already paid to build. Repairing a leaking abutment or replacing clouded roof panels is a very different sort of spend.
Five steps, agreed before we start.
Inspection & fixed quote
Roof type, frame condition, gutter arrangement and access assessed, with fixed itemised pricing covering roof, frames, gutters and glass before booking.
Preparation & protection
Furniture and planting around the structure protected, surrounding paving covered where needed, and safe reach-pole access set up with no load placed on the roof.
Roof & gutter clean
Panels cleaned at low pressure with purified water and appropriate detergents; box gutters, valleys and ridge cleared of moss, silt and leaf litter.
Frames, bars & glass
Frames, glazing bars, finials, cills and downpipes hand-detailed, then glass cleaned externally, and internally where requested, to a residue-free finish.
Check & handover
Drainage flow checked, any failed seals or cracked panels reported with photographs, then a walk-round and before-and-after images.
Specific outcomes, not vague promises.
Daylight restored
Clean panels transform how bright and usable the room feels: the whole point of the structure.
Leaks prevented at the source
Clearing box gutters and valleys addresses the most common cause of conservatory water ingress.
Seals protected
No pressure jetting means no water driven past gaskets and no seal stress.
Streak-free glass
Purified water dries residue-free, so there is no spotting or smearing after the first rain.
Everything, not just the glass
Roof, frames, bars, finials, cills, gutters and downpipes covered in one visit.
Problems flagged early
Cracked panels, failed seals and slipped flashings photographed and reported rather than washed over.
Materials, methods and where each applies.
Roof types and correct method
The roof dictates almost everything about how a conservatory is cleaned.
- Polycarbonate multiwall: scratches and clouds easily; low pressure, soft brush, no abrasives, and algae cleared from the flutes and end caps
- Glass and self-cleaning glass: cleaned with purified water only, since detergents can affect self-cleaning coatings
- Lantern roofs and orangery glazing: hand-detailed around the bars and upstand, where growth concentrates
- Tiled and solid conversions: cleaned like a small roof, with soft washing where moss has taken hold
- UPVC and aluminium frames: cleaned appropriately for the finish, with restorative treatment where oxidation warrants it
Box gutters, valleys and the abutment
Where a conservatory meets the house there is normally a box gutter or valley that collects everything shed from the main roof. It is out of sight, rarely inspected and consistently the point at which conservatories leak. We clear it as standard, test that water flows away, and photograph the condition so you can see what was in there and what it looks like now.
Internal glass and condensation
Cleaning inside as well as out makes a substantial difference to how the room reads, particularly on a lantern or a full glass roof. Persistent misting between panes, however, is a failed sealed unit rather than dirt, no cleaning will resolve it. Where we see it, we identify it clearly so you can price replacement glazing rather than repeatedly paying to clean an unfixable problem.
Frequency and seasonal timing
Most conservatories benefit from an annual clean, ideally in spring before the room comes back into daily use, with a gutter and valley check in late autumn on properties under tree cover. Shaded structures and those under overhanging trees green up quickly and are better served twice a year.

Conservatory Cleaning, straight answers.
How much does conservatory cleaning cost?
Pricing reflects size, roof type, whether internal glass is included and the gutter arrangement. Every quote is fixed and itemised before booking.
Do you clean the roof as well as the glass?
Yes: roof panels, ridge, glazing bars, frames, finials, box gutters and downpipes are all included, because cleaning only the vertical glass barely changes how the room feels.
Will you scratch my polycarbonate roof?
No. Polycarbonate is cleaned with soft brushes and purified water at low pressure, with no abrasive products and no contact load placed on the panels.
Can you clean the inside of the glass too?
Yes, on request. Internal cleaning makes a big difference on lantern roofs and full glass roofs and is quoted as a separate line item.
My conservatory leaks: will cleaning fix it?
Often, yes, if the cause is a blocked box gutter or valley, which it usually is. If the cause is a failed seal or flashing we will tell you and photograph it rather than claim otherwise.
How often should a conservatory be cleaned?
Annually for most, twice yearly under trees or in heavy shade. Spring is the ideal time, before the room comes back into regular use.
Is it safe to walk on the roof?
No, and we never do. All work is carried out from ground level with reach poles and appropriate access equipment.
Will the panels look new again?
Green film, silt and streaking come off completely. Panels that have clouded internally or crazed with UV age will improve but cannot be restored by cleaning, and we say so before quoting.
Do you clean orangeries and glass extensions too?
Yes, including lantern roofs, flat roof glazing, bifold and sliding door glass and the surrounding frames.
Which areas do you cover?
Based in Cheshire and covering the whole North West: Greater Manchester, Merseyside, Lancashire, Cheshire and into North Wales.
